Lotteries are specifically called out as illegal when used to incentivize voting or voter registration. By making a lottery only for registered voters, he is violating that law. The petition is a smoke screen, but it doesn’t actually negate the fact that this is a lottery for registered voters.
That’s why they switched to saying they were sponsors, they were trying to avoid lottery regulations. Unfortunately for them, you can’t make it legal retroactively by changing your story.
Just to be clear, this wasn’t the judge ruling that it was legal, it was the judge deciding not to issue an emergency order immediately halting the lottery. I’m honestly not surprised given the fact that there is only a day left and the damage is already done.
If there was any doubt that they were using this to get people to register to vote, this added detail should make it pretty clear. They were telling people who weren’t registered to register in order to get paid / enter a lottery.
